Simulating the Big Bang

DEFROST is a numerical code for simulating preheating of the Universe after the end of the inflation.
It is small, easy to modify, very fast, and fully instrumented for 3D visualizations.
DEFROST was written by Andrei Frolov for his early Universe research.
The source code is published and distributed under the terms of
GNU Public License.
